CVE-2026-93556 PUBLISHED

Direct references to unsafe objects (IDOR) in Tankuam Places by Kompini

Assigner: INCIBE
Reserved: 18.09.2026 Published: 22.09.2026 Updated: 22.09.2026

The ‘/password/guardarClau/recover’ endpoint accepts the ‘usuariId’ parameter, which specifies the account whose password is to be changed. The JWT token for the recovery process is not validated against the user specified in that parameter. An unauthenticated attacker could manipulate the identifier and reset the password for any account, including administrative accounts, which could allow them to take control of the account.
